1.	in a house two 60W electric bulbs are lighted for 4 hours and three 100W bulbsfor 5 hours everyday calculate the electric energy consumed in 30 days
Answer» Explanation: $\boxed{GIVEN}$ in a house two 60W BULB are lighted for 4hour The electric enery consumed in 1 DAY is $energy = power \times time \: taken$ $energy = 60w \times 4hour \times 2$ $energy = 480joule$ now three bulbs of 100w is lighted for 5hours the electrical energy consumed is $energy = 100w \times 5hour \times 3$ $energy = 1500joule$ the total electrical energy consumed in 1 day $\boxed{1500+480=1980joule}$ The electrical energy consumed in 30day $energy = 1980joule \times30days$ $\boxed{59,400joule}$
